如何從Windows Phone 7應用程序發送電子郵件

Question

在我的Windows Phone 7應用程序中，我想發送一封電子郵件，其中郵件正文應包含上一頁的數據。

private void Email_Send(object sender, RoutedEventArgs e)
{
EmailComposeTask emailComposeTask = new EmailComposeTask();

emailComposeTask.Subject = "message subject";
emailComposeTask.Body = "message body";
emailComposeTask.To = "recipient@example.com";
emailComposeTask.Cc = "cc@example.com";
emailComposeTask.Bcc = "bcc@example.com";
emailComposeTask.Show();
}

現在在正文部分我想要上一頁的數據。 那怎么做？

if (this.NavigationContext.QueryString.ContainsKey("school_name"))
{
//if it is available, get parameter value
school = NavigationContext.QueryString["school_name"];
school.Text = date;
}

請告訴我如何傳遞價值

Answer 1

嘗試這個：

emailComposeTask.Body = + school;

Answer 2

嘗試這個

private void Email_Send(object sender, RoutedEventArgs e)
{
string previousValue = string.empty;
if (NavigationContext.QueryString.ContainsKey("school_name"))
      previousValue = NavigationContext.QueryString["school_name"];
EmailComposeTask emailComposeTask = new EmailComposeTask();
emailComposeTask.Subject = "message subject";
emailComposeTask.To = "recipient@example.com";
emailComposeTask.Cc = "cc@example.com";
emailComposeTask.Bcc = "bcc@example.com";
emailComposeTask.Body = previousValue ;
emailComposeTask.Show();
}
